I am currently running simulation of rotating airfoils using the cyclicAMI Mesh. For previous runs (different mesh) I had no problem restarting the run if it blew or ran out of time from the latestTime. I then changed the number of airfoils from 3 to 2 in my mesh while keeping every other parameter the same. Now when I try to restart the run I get this error:

Floating point exception
I tried to run it both it serial and parallel and the same error happens. I tried both refine and coarsen my mesh and change the number of points on the AMI boundary. Since everything else is consistent from older runs in the 0/ system/ and constant/ directories except the mesh I just assumed that had to be the problem.

Can someone help me try to figure out what these errors mean so I can try to see where the error is actually occurring, or if anyone has run into a similar problem have any suggestions for me????

I have faced similar problem couple of times.

I guess it is the problem with your memory where openFoam is installed. I guess there is no sufficient space to write the files further.

I usually delete my previous cases and then make some free space and I run the case again the case works fine.

I am not sure if it works, but give it a try
